GENERAL
The La Marche Model TPS is a controlled ferroresonant float charger designed to power a load while
charging a battery.
The Model TPS is a filtered and may be used without a battery.
The all solid state electronic control circuit provides excellent line-load voltage regulation, current
limiting, and a power failure relay with light and Form “C” contacts.
The Model TPS is available in a wide range of single and three phase a.c. input voltages, with 24 volt, 48
volt and 130 volt d.c. outputs in output currents ranging from 6 to 100 amps.

OUTPUT RATINGS
2.1 D.C. VOLTAGE
The TPS series rectifiers provide separate voltage adjustments for floating or equalizing lead or nickel
cadmium cells. The float or equalize mode of operation is selected by a switch located on the front of
the rectifier.
The factory settings are as follows:
FLOAT VOLTAGE
EQUALIZE VOLTAGE
2.17 volts/cell (Lead)
2.33 volts/cell (Lead)
1.40 volts/cell (N.C.)
1.55 volts/cell (N.C.)
2.2 VOLTAGE RANGE
FLOAT
EQUALIZE
2.12 - 2.3 volts/cell +/- .1 volts (Lead)
2.25 - 2.40 volts/cell +/- .1 volts (Lead)
1.39 - 1.45 volts/cell +/- .1 volts (N.C.)
1.5 - 1.60 volts/cell +/- .1 volts (N.C.)
2.3 OUTPUT CURRENT
Single Phase Inputs
6, 12, 16, 20, 25, 30, 35, 50, 75, 100, AMPS
24Vdc, 48Vdc, or 130Vdc
Three Phase Inputs
75, 100, AMPS
24Vdc, 48Vdc, or 130Vdc
2.4 REGULATION
Steady state output voltage remains within +/- ½% of rated voltage for any load current from no load
to full load and for input voltages within the rated range.
